Am I being silly?

We went to the fireworks tonight and I suddenly thought, what if this harms the baby in any way!!! And now I am soooo worried that all the loud bangs would have scared him/her and there's something wrong.

I know I am being silly, but would s/he have heard anything in there? Did anyone else go to fireworks tonight?

I'm not sure when hearing develops, but I'm pretty sure at about 16 weeks they don't react to outside sounds yet. Panic not honey, my little one's been to all sorts of loud things and never seems to be bothered in the slightest! x x x
